Maybe you should consider reading the bug report before replying to it :-\
Supposedly this is a D3D regression. As for the actual exception, 0xc0000092 is
a floating point exception. e6611e22fb037a879205f1330d1a3485f9f18705 may have
some effect on that, so it makes sense to retest this with current git.
